Application module: Class of product | ISO/TS 10303-1077:2005(E) © ISO |
ISO 10303 is an International Standard for the computer-interpretable representation of product information and for the exchange of product data. The objective is to provide a neutral mechanism capable of describing products throughout their life cycle. This mechanism is suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases, and as a basis for archiving.
This part of ISO 10303 specifies an application module to record the existence of a class of product.
Membership of a class of product may indicate the nature of an individual product.
A class of physical object can be more or less generic. A class of physical object can involve different types of criteria, as illustrated below
the form of a product;
EXAMPLE 1 'Multi-stage centrifugal pump' is a class of product.
the possible use of a product;
EXAMPLE 2 'Pump' is a class of product.
EXAMPLE 3 'Fire water pump' is a class of product.
EXAMPLE 4 'Fire water pump in complex A' is a class of product.
the nature and structure of the product at scales smaller than those of normal engineering concern.
EXAMPLE 5 'SG cast iron' is a class of product.
the grouping of individual products for administrative purposes;
EXAMPLE 6 '1999 production run of pump type XYZ_123' is a class of product.
EXAMPLE 7 'Pumps maintained by J. Bloggs and Co. under contract PM_1234' is a class of product.
the specification of a product, for a particular engineering activity.
EXAMPLE 8 'J. Bloggs pump type XYZ_123' is a class of product. This class, defined by J. Bloggs and Co., may be specified in a purchase order.
Clause 1 defines the scope of the application module and summarizes the functionality and data covered. Clause 3 lists the words defined in this part of ISO 10303 and gives pointers to words defined elsewhere. The information requirements of the application are specified in Clause 4 using terminology appropriate to the application. A graphical representation of the information requirements, referred to as the application reference model, is given in Annex C. Resource constructs are interpreted to meet the information requirements. This interpretation produces the module interpreted model (MIM). This interpretation, given in 5.1, shows the correspondence between the information requirements and the MIM. The short listing of the MIM specifies the interface to the resources and is given in 5.2. A graphical representation of the short listing of the MIM is given in Annex D.
In this International Standard, the same English language words may be used to refer to an object in the real world or concept, and as the name of an EXPRESS data type that represents this object or concept.
The following typographical convention is used to distinguish between these. If a word or phrase occurs in the same typeface as narrative text, the referent is the object or concept. If the word or phrase occurs in a bold typeface or as a hyperlink, the referent is the EXPRESS data type.
The name of an EXPRESS data type may be used to refer to the data type itself, or to an instance of the data type. The distinction between these uses is normally clear from the context. If there is a likelihood of ambiguity, either the phrase "entity data type" or "instance(s) of" is included in the text.
Double quotation marks " " denote quoted text. Single quotation marks ' ' denote particular text string values.
